Lions LE Jason Jones tore the patellar tendon in his left knee in Sunday's Week 3 win over the Redskins and is done for the season. Jones was carted off the field in the second quarter after his knee gave out on a non-contact play. The 27-year-old wasn't creating much pressure on the quarterback through two-plus games, and he was near the bottom of Pro Football Focus' 4-3 defensive end rankings. However, he was a valuable veteran presence up front. Willie Young and Israel Indonije will fill in at left end for the remainder of the season. Jones signed a three-year deal in March.
