Stewart (hamstring) will miss the next two weeks and could begin the season on the disabled list, the Pittsburgh Tribune-Review reports.

Stewart is in line for additional playing time over 2014 if he can stay healthy. He batted .294/.362/.331 in 154 at-bats last season, though only five of his 40 hits went for extra bases. Tony Sanchez would likely take his backup spot if Pittsburgh decides to disable Stewart.

Stewart is suffering from a minor hamstring issue, but manager Clint Hurdle hopes he will return Tuesday, Travis Sawchik of the Pittsburgh Tribune-Review reports.

Stewart's injury appears to be minor, but it's worth noting in case it turns into something more. He's slated to serve as the Pirates backup catcher in 2015, but Tony Sanchez is also in the mix.

Stewart and the Pirates avoided arbitration by agreeing to a one-year, $1.225 million contract Friday, CBS Sports' Jon Heyman reports.

Stewart served as the Pirates' backup catcher last season and is the favorite to do so again in 2015. The Pirates' new primary catcher, Francisco Cervelli, has had trouble staying healthy in his career, so Stewart could see more action than reserve catchers typically do.

Stewart (wrist) was included on the Pirates' Wild Card roster.

Russell Martin (hamstring) is expected to start, but Stewart is healthy enough to assume his typical backup duties. Tony Sanchez will be available as well in case both players experience complications with their injuries.

X-rays on Stewart's left wrist came back negative, Rob Biertempfel of the Pittsburgh Tribune reports.

Stewart exited Sunday's game after his hand caught the backswing in one of pitcher Johnny Cueto's at-bats. No fractures were revealed, but he does have a serious bruise on his left hand, and should be considered day-to-day moving forward. Russell Martin (hamstring) will likely be ready for Wednesday's NL Wild Card matchup, but if not, Stewart would be the likely backup, provided the swelling goes down.

Stewart left Sunday's game with a hand/wrist injury, Bill Brink of the Pittsburgh Post-Gazette reports.

Stewart was hit on his hand on the backswing of a Johnny Cueto RBI hit, and had to be removed from the game as a result. Tony Sanchez came into the game to serve as his replacement. Sanchez could be in line to see extra work if a catcher is needed in a tiebreaker game Monday or Wild Card contest Wednesday, as fellow backstop Russell Martin is also nursing a hamstring injury.

Stewart went 2-for-4 with an RBI on Tuesday, raising his batting average to a season-high .283.

He only has 20 at-bats since June, but might be an option in daily leagues on days when scheduling is thin. For the season, Stewart is batting .283/.374/.313 with no homers and six RBI in 99 at-bats.

Pirates activated C Chris Stewart from the 15-day disabled list.

Stewart is returning from surgery to repair the meniscus in his right knee. He'll function as the primary backup behind starting catcher Russell Martin.

Chris Stewart (knee) could be activated from the disabled list by this weekend.

Stewart has played a couple rehab games, including the entirety of a four-hour game Sunday, "and he said he felt good [Monday], which is a good sign," Pirates manager Clint Hurdle said. Tony Sanchez will return to Triple-A once Stewart is ready.

Pirates placed C Chris Stewart on the 15-day disabled list with a right knee injury.

Stewart had surgery on his right meniscus in mid-March and is expected to miss the first 3-4 weeks of the regular season. Tony Sanchez will serve as the backup to starting catcher Russell Martin in the early going.

Chris Stewart is expected to need 4-6 weeks of recovery time from Wednesday's right knee surgery.

Stewart had his right meniscus shaved down. It was a minor procedure, but the 32-year-old catcher will still need about a month of rehab. The Yankees could roll with Tony Sanchez as Russell Martin's backup.

Chris Stewart underwent a minor surgical procedure on his right knee Wednesday.

The surgery wasn't considered invasive and no further procedures will be required. It's unknown at the present hour if Stewart, acquired from the Yankees in December for a player to be named later or cash considerations, will require a DL stint to begin the season. If that's the case, it'll clear room for Tony Sanchez to serve as Russell Martin's backup.

Chris Stewart will visit Dr. James Andrews to have his right knee examined, with surgery seen as "probable."

It's not clear how long he'd be sidelined, but obviously even a minor operation would rule him out for Opening Day. That would clear room for Tony Sanchez to serve as Russell Martin's backup.

Pirates and C Chris Stewart avoided arbitration by agreeing to a one-year contract.

The financials aren't known. Stewart was acquired from the Yankees earlier Monday and will likely enter the 2014 campaign as Russell Martin's backup.

Pirates acquired C Chris Stewart from the Yankees for a player to be named later or cash considerations.

Stewart was likely going to be non-tendered by the Yankees after batting just .211/.293/.272 in 340 plate appearances this season. He'll be in the running for the backup job behind Russell Martin in Pittsburgh -- Michael McKenry being his primary competition.

According to ESPN's Buster Olney, the Pirates are close to acquiring Yankees catcher Chris Stewart.

Stewart was a non-tender candidate in New York and the deadline for those contract decisions is on Monday night. The 31-year-old backstop hit .211/.293/.272 with four homers and 25 RBI in 340 plate appearances this past season for the Yankees. He can back up starting catcher Russell Martin next summer in Pittsburgh.

Chad Jennings of LoHud.com believes that Chris Stewart is likely to be non-tendered by the Yankees.

Jennings notes that the Yankees have already made it clear that Francisco Cervelli will return next season, and that there's no reason to send Austin Romine back to Triple-A. Rather than spending guaranteed money on a defensive-first option like Stewart, they should be able to secure a similar type of player on a minor league deal.

Chris Stewart (foot) returned to the Yankees lineup on Tuesday.

He's batting ninth and playing catcher against Baltimore and Miguel Gonzalez. Stewart was removed from Sunday's game after sustaining a bruised foot on a hit by pitch.

Chris Stewart is expected to miss a few games after bruising his foot in Sunday's game against the Red Sox.

Stewart was removed from the game after being hit by a pitch. Austin Romine replaced him, and figures to be the biggest beneficiary while Stewart is sidelined. If you're looking at either of these options, you're really scraping the bottom of the barrel in deep two-catcher mixed leagues.

Chris Stewart will undergo X-rays on his left foot after leaving Sunday's game following a hit by pitch.

The Yankees are calling the X-rays precautionary. Austin Romine came in for Stewart Sunday.
