The Ravens have activated TE Charlie Kolar from IR. Kolar has yet to play a game this season because of a sports hernia, but he has been practicing for several weeks. “He’s looked really good,” HC John Harbaugh told the team’s website. “He’s a young player, and he missed a lot of time during training camp so he’s still developing, but he’s out there [and] he looks good. He’s so talented, he’s so big, he has great hands. He had three good weeks of practice, so I anticipate him being brought up this week.” Kolar will have to contend with a crowd at TE, including Mark Andrews' expected return from injury, Josh Oliver, Nick Boyle and fellow rookie Isaiah Likely. It'll be tough for Kolar to carve out a significant role the rest of the way -- perhaps even to make the game-day roster.
