OWINGS MILLS, Md. — Mark Andrews may not yet know whether he’ll play in Saturday’s divisional-round tilt with Houston, but the Ravens tight end even being in this position is the result of two months of strenuous rehabilitation. Speaking to reporters for the first time since mid-November on Wednesday, Andrews said there are numerous people to thank as he works his way back from a significant left ankle injury that required surgery in November, but “big, big jumps” in progress and even the use of a hyperbaric chamber — compliments of his girlfriend’s family — have helped position him to return for what Baltimore hopes will be a Super Bowl run. Managing the swelling of his ankle remains a daily challenge, but the three-time Pro Bowl selection says he’s feeling “very positive” about his progress and “usually” bouncing back the way he needs to. “I think it’s how I feel at the end of the day,” said Andrews about his chances of playing against the Texans. “Just knowing how good this team is, how good our players are, how good our tight ends are, if I feel like I’m going to be helpful to the team, I’m going to go.
