CHARLOTTE, N.C. — The Carolina Panthers are 1-0 but they were dealt a significant blow Tuesday as the team announced that tight end Greg Olsen re-fractured his foot during Sunday's home opener against Dallas.

Olsen left the game in the first half after stepping on the foot of a Cowboys defender. He was seen on the sideline during the game in a walking boot with crutches. On Monday, head coach Ron Rivera didn't disclose any details on Olsen's injury.

According to the team, there are no plans for Olsen to have surgery on the broken foot and he will be evaluated on a monthly basis. Last year, Olsen missed eight games with the same injury he suffered early in the season.

Rookie Ian Thomas is expected to fill-in for Olsen as the No. 1 tight end for the time being. Rivera said the rookie is "pretty well prepared" to step into the role Monday.
