Louis Delmas injury cause for concern

During my time at the Detroit Lions' training camp, I couldn't find much reason for alarm about the state of safety Louis Delmas' groin injury. I would say I'm close to having a change of heart.

More than two months after suffering the injury, Delmas remains on a limited practice schedule and isn't sure if he'll appear in Saturday's preseason game against Denver. Thursday, he told reporters he is "very" frustrated with the injury, and coach Jim Schwartz said Delmas isn't at a point where he can participate in back-to-back practices at full strength.

Schwartz has maintained throughout the summer that the Lions are following a long-term plan to allow the injury to heal fully before the regular season begins. But at some point, you would like to see Delmas go through a full week of practice. That's the only way to know for sure if the groin can withstand a regular-season routine.

In case you hadn't noticed, the Lions started undrafted rookie Randy Phillips in Delmas' position on Saturday in Pittsburgh. When I was at Lions camp, Phillips wasn't even on the roster. The starter at that time was Marvin White, who has since been released.
