Cobb is working out for the Lions on Tuesday, Dave Birkett of the Detroit Free Press reports.

EDGE Analysis

Cobb's trying out alongside fellow running backs Josh Robinson and Bronson Hill, so it seems the Lions may not be content with their depth behind Ameer Abdullah and Theo Riddick (wrist) at this juncture. Cobb is easily the most accomplished of the three try-out players, as the 2015 fifth-rounder carried 52 times for 146 yards and one touchdown his rookie season with the Titans while Robinson and Hill only have 19 career carries combined. However, Cobb has averaged just 2.8 yards per carry and is a downhill runner who's likely a better fit in a power run scheme, something the Lions don't employ.

Cobb was waived by Chicago on Monday, Brad Briggs of The Chicago Tribune reports.

EDGE Analysis

Cobb spent 2016 on the Bears practice squad but never appeared in a regular season game. He'll look to catch on with another team in 2017.

Cobb signed a future/reserve contract with the Bears on Wednesday, Patrick Finley of the Chicago Sun Times reports.

EDGE Analysis

Cobb spent a majority of the season on the Bears' practice squad and will now compete for a spot on the 53-man roster next season. In 2015 he spent seven games with the Titans, rushing for 146 yards and one touchdown on 52 attempts.

Cobb signed with the Bears on Tuesday.

EDGE Analysis

Cobb heads to Chicago after spending time on the Steelers' practice squad this season. A 2015 fifth-round selection by the Titans, Cobb figures to compete with Ka'Deem Carey for reserve carries behind rookie Jordan Howard, as Jeremy Langford continues to nurse an ankle injury.

Cobb signed with the Pittsburgh practice squad Wednesday, NFL.com Ian Rapoport's reports.

EDGE Analysis

A fifth-round selection last year, Cobb fell out of the Titans' plans after the team traded for DeMarco Murray and drafted Derrick Henry. Given Pittsburgh's lack of proven talent behind Le'Veon Bell and DeAngelo Williams, it won't be surprising if Cobb eventually finds his way to the active roster. It would help his cause quite a bit if he could contribute on special teams.

Cobb worked out for the Patriots on Friday, ESPN's Field Yates reports.

EDGE Analysis

Cobb was released by the Titans earlier this week, but could be a nice pickup for teams in need of help at running back. Although a calf injury limited him to just 146 yards in seven games played as a rookie, Cobb was a fifth-round pick only last year, and was only forced out of Tennessee due to new management's offseason additions of DeMarco Murray and Derrick Henry. As a result, the jury is still very much out on Cobb, thus making a team like the Patriots' interest in him not really surprising. That being said, it remains to be seen where he'll land ahead of this season.

Cobb was released by the Titans on Tuesday.

EDGE Analysis

With the offseason additions of DeMarco Murray and Derrick Henry, Cobb found himself as the odd-man-out of the Titans' backfield. The second-year man never lived up to the hype that made him a fifth-round draft pick just a season ago. He spent the first half of his rookie season on IR and only rushed for 146 yards in seven games once he returned. Given that he's only 23, Cobb could find work on a team looking to boost up their backfield.

Cobb was released by the Titans on Tuesday, Jim Wyatt of titansonline.com reports.

EDGE Analysis

Tennessee opted to part ways with its 2015 fifth rounder Tuesday mainly due to depth complications at running back. The Titans acquired both DeMarco Murray and Derrick Henry in the offseason to dominate the team's rushing attack in 2016, making Cobb an expendable piece. The 23-year-old still has time to land with another club before the regular season rolls around, but time is definitely ticking.

Cobb rushed twice for one yard, and went without a target in Saturday's preseason win over the Raiders.

EDGE Analysis

Cobb got more action than Bishop Sankey, but both were outplayed by Derrick Henry, DeMarco Murray, Antonio Andrews and Dexter McCluster. The second-year running back's chances of making the Titans roster are very much in doubt after he averaged a paltry 2.8 yards per carry on 52 attempts as a rookie.

Cobb gained 27 yards on six carries and one yard on one reception, also losing a fumble, in Saturday's preseason game against the Panthers.

EDGE Analysis

Cobb didn't get a carry until midway through the third quarter, and he promptly responded by losing a fumble. He did partially redeem himself later in the game, but it wasn't enough to move him off of the roster bubble. Cobb is competing with Antonio Andrews, Bishop Sankey and David Fluellen for what will likely just be one roster spot.,
