Oakland receiver Randy Moss is questionable for the Raiders' game against St. Louis after twisting his ankle. Moss injured the ankle after a 16-yard catch on the second play of the second quarter in Sunday's loss to the Bengals. Moss limped off the field and did not return. "When you turn an ankle over like that, it can be difficult, especially when you're a so-called skill guy making those cuts," coach Art Shell said Monday.
