Friday is the day of the week when the injury status of players are revealed. We tend to think short term: Is the quarterback questionable? Is the running back a game-time decision?

Then you hear about Browns guard Jason Pinkston and realize that not all the injuries are simply a pull or bruise. Pinkston has a blood clot in his lung, a league source told The Plain Dealer. He will undergo "aggressive treatment," the paper reported. Our thoughts go out to Pinkston during this difficult time.

The Browns do not know when the second-year guard will be released from the hospital or cleared to return.

"We're definitely concerned and our thoughts are with him," said left tackle Joe Thomas, who starts beside Pinkston on the line. "Obviously, it's a little bit scary, but I guess we're definitely going to keep in touch with him and hopefully things will be all right."

Pinkston started last week's win over Cincinnati but wasn't feeling well and was replaced by John Greco, who played the entire second half. Pinkston practiced as recently as Wednesday but missed Thursday's workout and was listed on the team's injury report as being out with an "illness."

Greco was one of the players who visited Pinkston in the hospital.

"We saw him last night," Greco said. "We went to say hi to him, just to keep his spirits up a little bit and tell him we were with him."
