What It Means:

Bell will be eligible to return in Week 5. The Jets signed Kalen Ballage to the active roster in a corresponding move. Frank Gore and Josh Adams will likely split most of the backfield work with Bell sidelined. Lamical Perine (ankle) could also potentially contribute in Week 2 versus the San Francisco 49ers if healthy. Ballage may wind up with a role out of necessity. Bell rushed 6 times for 14 yards and caught 2 passes for 32 yards in Sunday's game against the Buffalo Bills before departing with a hamstring injury.

Bell was the Jets' least efficient runner in Week 1, according to numberFire's metrics. He averaged -0.23 Rushing Net Expected Points per play, compared to 0.00 for Gore and 1.22 for Adams. The 49ers were tagged for the second-most rushing yards (180) in Week 1 and check out as the third-worst defense against the run in our advanced rankings through the first week of games.
