Grubbs had a procedure on the ankle in 2009 as well, but has been remarkably resilient. He started 60 of the 64 games he has played since being drafted in the first round in 2007. The 64-game streak is the team's fourth-longest active streak.

Thin at wide receiver

Injuries have depleted the Ravens at wide receiver enough that in one drill Tuesday, Justin Harper and Brandon Jones worked with the first team. Harper spent the past two years on the practice squad, and Jones, a five-year NFL veteran, did not play in 2010.

Sidelined were second-round pick Torrey Smith and veteran James Hardy, both with apparent hamstring tightness. Anquan Boldin is the only receiver in camp who played for the Ravens last season, and he takes his normal turns.

Cameron said he hopes both Smith and Hardy can return to practice Wednesday.

Reid settles in

Cameron said rookie offensive tackle Jah Reid had his best day of practice after working through the predictable early transition.

"All the [young] linemen were overwhelmed, because it is, it's overwhelming," Cameron said. "But I think [Reid] settled in today. I saw a little difference. Things weren't as confusing. It looks like he corrected some mistakes from [Monday], and that is a great sign when young guys start correcting mistakes this early on."

End zone

Also sitting out Tuesday's practice were cornerbacks Jimmy Smith (groin) and Domonique Foxworth (knee). … Undrafted rookie wide receiver Hakeem Moore (Towson) hasn't worked since Friday because of an apparent injury. ... The Ravens waived undrafted rookie offensive tackle Alex Solot. … Kicker Billy Cundiff hit field goals from 32, 39, 50 and 59 yards before missing from 45 — his first miss of camp. … The Ravens were 1-for-2 in goal-line offense. Starting from the 3-yard line, Ray Rice powered into the end zone in two carries, but rookie Anthony Allen was unable to score in three tries from the 3. … Safety Ed Reed wore Matt Stover's No. 3 instead of his own No. 20.
