Philadelphia Eagles quarterback Kevin Kolb has agreed to a one-year contract extension worth $12.26 million dollars guaranteed, Adam Caplan of Scout.com reports.

According to Caplan, Kolb will receive a $10.7 million dollar signing bonus, and 30% increases over his 2010 and 2011 base salaries, the maximum increase allowed.

A second-round pick (36th overall) out of the University of Houston in 2007, Kolb has appeared in 12 games, including two starts, during his first three seasons in the NFL. The 6-3, 218-pound quarterback has completed 60.8% of his passes for 885 yards, four touchdowns and seven interceptions, compiling a passer rating of 68.9.

Kolb got his first NFL starts early in the 2009 campaign, after McNabb was sidelined by broken ribs in the season-opener. Kolb attempted 51 passes against the eventual NFC Champion New Orleans Saints in his first NFL start, and the inexperienced Kolb predictably struggled, tossing three interceptions in Philadelphia's 48-22 loss. The following week against Kansas City, Kolb appeared more composed, completing 24-of-34 passes for 327 yards and a pair of touchdowns, but more importantly, played turnover-free football.
