Jerome Bettis, the NFL's rushing leader, most likely will miss division-leading Pittsburgh's game against the Jets on Sunday because of groin and hip injuries. Bettis was listed Tuesday as doubtful, meaning there is a 25 percent chance he could play. Coach Bill Cowher said even that might be overestimating his chances. "We'll see how he is by the end of the week but, by listing him as doubtful, you can see where I'm heading," Cowher said. An MRI test on Bettis' hip showed no serious injury. He also was bothered by a sore groin and abdomen before coming out of the Steelers' 21-16 victory Sunday over Minnesota after gaining 81 yards in three quarters. Bettis said there is some internal bleeding but it is not serious.
