Chargers OLB Melvin Ingram returned from a 2013 ACL tear suffered on May 14 to play in San Diego's final four regular season games. Ingram also contributed in the playoffs, starting twice and compiling six tackles to go with an interception. Cowboys MLB Sean Lee's ACL tear occurred on May 27, so he's just two weeks behind Ingram. Dallas has yet to place Lee on injured reserve, perhaps in hopes of a late-season impact. The Cowboys would have to stash Lee either on the reserve/PUP list or I.R./designated for return.
