Slowly but surely, the Carolina Panthers are rebuilding their depleted wide receiver corps. The Panthers have signed free agent wideout Jason Avant to a one-year contract, the team announced Monday. Terms of the deal were not disclosed. Avant becomes the third free agent receiver to sign with the Panthers, joining former Steelers red-zone specialist Jerricho Cotchery and ex-Tampa Bay wideout Tiquan Underwood. The Panthers cut franchise receiving leader Steve Smith last month and saw three other receivers -- Brandon LaFell, Ted Ginn Jr. and Domenik Hixon -- leave in free agency. And while they still don't have a true No. 1 receiver -- Panthers coach Ron Rivera says they don't necessarily need one -- they picked up a sure-handed, possession receiver in Avant, who spent his first eight seasons in Philadelphia. Avant, who turns 31 in two weeks, was cut last month in a move that saved the Eagles more than $3 million in salary cap space. Avant, Philadelphia's fourth-round pick from Michigan in 2006, ranks 11th in Eagles history with 297 catches for 3,646 yards and 12 touchdowns.
