After the season, with one year left on his rookie contract, Jackson believed he was underpaid and held out of training camp. On August 21, 2008, Jackson officially ended his holdout by signing a six-year contract worth a maximum of $49.3 million, including a $11.4 million signing bonus and $21 million guaranteed. Because the final two years of the deal (2012 and 2013) can be voided based on Jackson's performance, it could become a three-year extension worth $29.3 million instead. Either way, signing the contract made him the highest-paid running back in the NFL. In Week 7, against the Dallas Cowboys, he had 25 carries for 160 yards and three rushing touchdowns. His performance against the Cowboys gave him his second NFC Offensive Player of the Week award. He closed out the season with 161 rushing yards and two rushing touchdowns against the Atlanta Falcons. Overall, he finished the 2008 season with 1,042 rushing yards, seven rushing touchdowns, 40 receptions, 379 receiving yards, and one receiving touchdown.
