The cornerback played just six games last season before sustaining an anterior cruciate ligament tear in October.
Defensive coordinator Dean Pees told CSN Baltimore: "He makes plays. He's a good tackler. It looks like he's a buck-fifty out there, but the guy throws his body around. He thinks he's a linebacker.
"The other part of it is just the way he plays, with the tenacity that he plays with. It just brings an extra spark to that whole secondary."
Webb managed 24 tackles and one interception before picking up the injury last season.
