It was a tough day first day of camp practice for the Tampa Bay Buccaneers. It already has been widely reported that wide receiver Arrelious Benn suffered a knee injury that will sideline him for about a month. But, on top of that, cornerback E.J. Biggers also is going to miss some practice time.

A league source told ESPN.com that Biggers suffered a broken bone in his foot Friday.

Both injuries have the potential to cause problems. Biggers seemed likely to be the No. 3 cornerback behind starters Aqib Talib and Eric Wright. There’s not much depth beyond Biggers, and that opens some possibilities in the nickel package if the injury causes him to miss any regular-season time.

The Bucs have moved veteran cornerback Ronde Barber to free safety. There’s been talk that Barber could slide to nickelback and line up with slot receivers on passing downs and Cody Grimm could take his place at free safety in those situations. If Biggers is healthy for the regular season, he gives the Bucs options. If he’s not ready, the Bucs might have to shuffle Barber and Grimm. The Bucs also claimed cornerback Desmond Marrow off waivers from Houston on Friday, but I don't know if he's a serious threat to make the roster.

Benn’s injury also is significant, even though the Bucs have some depth at wide receiver. Benn was considered to be in the mix to start opposite Vincent Jackson. But the Bucs have several other options with young wide receivers such as Mike Williams, Preston Parker and Sammie Stroughter.
