The New York Post reports Jets RB Joe McKnight was arrested in New Jersey last week for outstanding warrants after police pulled him over for speeding and changing lanes without signaling.

McKnight was arrested on July 30, on a Jets day off from camp. Police found he had blown off a $200 ticket for failing to produce an insurance card, and another $120 fine for failing to observe a traffic signal. Apparently, McKnight obeys traffic law about as well as he plays running back. He suffered a concussion at Friday's practice, and has not participated in training camp since.

Jets RB Joe McKnight is sidelined by an "apparent concussion" in camp.

McKnight might be more on the roster bubble were Chris Ivory healthy and Mike Goodson in camp. Instead, Ivory is injured and Goodson has yet to report, leaving Bilal Powell to work as the starter. McKnight could still wind up losing his roster spot, but for now he's hanging on and should make it to final cuts.

Jets activated RB/KR Joe McKnight from the active/PUP list.

McKnight failed his pre-training camp conditioning test, but was cleared to practice Friday. Entering a contract year, he's competing for a roster spot behind Chris Ivory, Bilal Powell and Mike Goodson.

Jets placed RB/KR Joe McKnight on the active/PUP list.

He flunked his conditioning test on the first day of camp. McKnight's contract year is already off to a bad start with his roster spot hanging by a thread behind Chris Ivory, Mike Goodson, and Bilal Powell on the Jets' depth chart.

Jets RB/KR Joe McKnight is certain he'll make the final roster.

"They're going to have to kill me to take my spot," McKnight said. "So, whoever they bring in, I don't care. I'm just going to make it a point to prove I'm going to be here." McKnight is entering the final year of his rookie deal, and he says new OC Marty Mornhinweg has been working him in the slot, too. The 25-year-old has averaged 4.5 YPC on 112 career totes and isn't a legit offensive threat.

Joe McKnight considers himself a legitimate contender for the Jets' starting running back job, and vows to be "a lot better" in 2013.

"I made that promise to myself," McKnight said. "If not, I'm going to die trying. I'm nowhere near close to where I want to go." McKnight also claims to have never had a single conversation with former OC Tony Sparano, but that he "loves" new OC Marty Mornhinweg. McKnight's fire is admirable, but he should remain a gadget player/special teamer this season.

Jets RB Joe McKnight rushed once for two yards in the team's Week 17 loss to Buffalo.

McKnight gained 179 yards on 30 carries (5.97 YPC) this season, but was curiously underutilized as a change-of-pace back behind plodders Shonn Greene and Bilal Powell. McKnight, also the Jets' primary kickoff returner, is still just 24 years old and due an affordable $575,000 in 2013. While he's almost certainly not the answer for the Jets' feature back woes, McKnight deserves a longer look in a complementary role from New York's next offensive staff.

Joe McKnight (ankle, illness) was downgraded to "DNP" in practice on Thursday.

McKnight was listed as a "full" participant on Wednesday with an ankle issue, so he was likely sent home sick on Thursday. He should be fine for Week 17 against the Bills as the Jets' No. 3 running back and kick returner.

Jets RB Joe McKnight was inactive in Week 14 after suffering three migraine headaches.

Coach Rex Ryan said his original plan was to keep three quarterbacks active -- Mark Sanchez, Tim Tebow, and Greg McElroy -- against the Jaguars, but the Jets were forced to deactivate McElroy and dress Kahlil Bell due to McKnight's migraines. McKnight has been thoroughly fantasy irrelevant this season.

Joe McKnight was taking reps at wide receiver on Monday.

Joe McKnight (ankle) is officially questionable for Thursday's game against the Patriots.

McKnight escaped Sunday's win over the Rams without setbacks, and will be active for New York's Thanksgiving nightcap with the Pats. He won't be in for more than 3-5 touches, however.

Joe McKnight (questionable, ankle) is expected to play in Sunday's game against the Rams.

Barring any setbacks, McKnight will return after missing last week's game. Bilal Powell (concussion) also received medical clearance Saturday and will continue to serve as Shonn Greene's backup.

Joe McKnight (ankle) is listed as questionable for Week 11 after getting in his third straight limited practice Friday.

McKnight expects to play against the Rams, but could end up a game-time call. Regardless, he's well off the radar in fantasy leagues.

Joe McKnight (ankle) and Bilal Powell (concussion) were limited in Thursday's practice.

McKnight is tentatively expected to return for Sunday's game. Although Powell resumed practicing, he was sporting a red non-contact jersey suggesting he's yet to gain full clearance.

Jets RB/KR Joe McKnight (ankle) was limited in Wednesday's practice, but expects to be active for Week 11.

McKnight was held out of Sunday's loss to the Seahawks, but with two weeks of rest under his belt, should be ready to go against the Rams. McKnight is averaging just 2.1 touches per game.

Jets RB/KR Joe McKnight (ankle) has been ruled out for Week 10.

McKnight tried to play through the injury two weeks ago, but suffered a setback in the game. He was limited in practice all week, and did not travel with the team to Seattle. Bilal Powell (shoulder) is listed as questionable, but coach Rex Ryan expects him to play as Shonn Greene's backup on Sunday.

Jets RB/KR Joe McKnight (ankle) is "unlikely" to play versus the Seahawks in Week 10.

McKnight aggravated his high ankle sprain by trying to play through it two weeks ago. Bilal Powell (shoulder) has returned to limited practice this week and appears to be on track to play as Shonn Greene's backup on Sunday.

Joe McKnight (ankle) did not practice Thursday.

McKnight continues to keep stress off his ankle sprain. If active against the Seahawks Sunday, he'll have a bit role off the bench behind Shonn Greene and possibly Bilal Powell (shoulder).

Joe McKnight (ankle) was absent from Wednesday's practice.

McKnight is capable of playing without practicing, but the fact he was held out with the Jets coming out of their bye isn't a good sign. The New York Daily News is "guessing" he'll be ready to play in Week 10 against Seattle.

Joe McKnight (ankle) is not expected to practice Wednesday.

It's concerning that McKnight is still not ready to practice as the Jets come out of their bye. The kick returner and change-of-pace back has been gutting it out through a serious ankle sprain since Week 6.
