The Carolina Panthers continued their offseason overhaul of the offensive line Thursday.
The team has signed free-agent guard Mike Pollak, who spent most of the past four seasons as a starter for the Indianapolis Colts. A second-round pick out of Arizona State in 2008, Pollak started 41 of 58 games for the Colts.
His signing came after the Panthers released veteran Travelle Wharton in a salary-cap move. The team re-signed Geoff Hangartner, the other starter from last season. The Panthers also think highly of Garry Williams, who was injured last preseason.
It’s expected the Panthers will go to camp and let Pollak, Hangartner and Williams compete for the two starting spots.
