As the Ravens began preparing for their season opener against the Houston Texans, star tight end Mark Andrews was absent from practice.

Andrews also missed multiple days of practice last week, but on Monday, Ravens coach John Harbaugh said there was still no need to push the “panic button,” and that Andrews would be back on the field Wednesday.

Andrews and cornerback Marlon Humphrey (foot) were the only players not at practice. Humphrey’s absence isn’t a surprise. He had foot surgery earlier in camp, and Harbaugh said it could keep him out through the early portion of the season.

Ravens quarterback Tyler Huntley was back at practice after a hamstring injury in the opening preseason game kept him sidelined for much of camp. Harbaugh said he would make a decision on Huntley after seeing how he practices on Wednesday. If Huntley isn’t prepared to play, Josh Johnson would serve as the backup. The Ravens could still have Huntley in uniform, though, as an emergency quarterback option that won’t cost them a game-day roster spot.

Linebacker David Ojabo, cornerback Kevon Seymour, and linebacker Tavius Robinson were also back at practice. Seymour was in uniform but working out with a trainer during team drills.
