INDIANAPOLIS -- Indianapolis Colts running back Frank Gore said Tuesday that he's still not happy about failing to record the ninth 1,000-yard rushing season of his career. Gore, who signed with the Colts last season after spending the first 10 years of his NFL career with the San Francisco 49ers, finished with 967 yards rushing last season.

"I'm not over it," Gore said. "I'm not going to be over it until I do it. I've been blessed that they kept me to get the opportunity to do it again. To go after my goals again, to be the one to get the 100 yards that they didn't have in years. To get that 1,000-plus yards [in a season]."

For years, the lack of a rushing game has been a sore subject for the Colts, who haven't had a 1,000-yard rusher since 2007. They also have gone 50 straight games without a 100-yard rusher, the longest streak since the Cincinnati Bengals went 67 straight games without one from 1992-97, according to ESPN Stats & Info.

Indianapolis has only had one 100-yard rusher, Vick Ballard, since selecting quarterback Andrew Luck in 2012. Gore rushed for more than 90 yards in a game just once last season.

"Now I got another opportunity to do it so from here on out," Gore said. "I just have to start taking care of my body, eating healthy, start training to get myself ready to try to go get it."
