extension Color Rush Christian McCaffrey Jersey , per reports The Carolina Panthers have reached a contract extension with center/guard Tyler Larsen, according to Jourdan Rodrigue of the Charlotte Observer. The extension is for two years and $4.4 million with $1.4 million guaranteed.What this means for the PanthersThis could potentially be a huge deal for the Panthers since Larsen is seen as a potential replacement for center Ryan Kalil, who is expected to retire at the end of the 2018 season. Larsen can also fill in at left guard, and with Amini Silatolu suffering a knee injury yesterday that will keep him out of action for several weeks/months, the Panthers could use all the depth they can get on the offensive line. Brendon Mahon is currently penciled in to be Silatolu’s replacement at left guard, but if the Panthers wanted to add more experience to the position they could certainly use Larsen as a fill-in for this season. My takeI think this is a great signing. The Panthers—at the very least—have a plan in place for the post-Kalil world that will begin in 2019. Larsen might not be the best center in the league, but he’s at least a solid depth option that the Panthers can rely on until they can find someone better.What do you think Youth DJ Moore Jersey , Panthers fans?
