Live blog: Senior Bowl practice

TideNation's Alex Scarborough is live blogging from Senior Bowl practice today in Mobile, Ala.

3:21 p.m. - Practice is officially over. Good work done today by the Alabama players who are hoping to be selected in the NFL Draft. Upshaw is probably the biggest winner if you had to name one. Smelley and Menzie also playing very well.

3:05 p.m. - Menzie and Smelley on kickoff return coverage. Upshaw and Vlachos getting a breather.

2:54 p.m. - As we reported earlier, Menzie is playing with a chip on his shoulder this week. He is well aware of his doubters and it's showing. He looks like a man on a mission and is not quitting on the play. He just ran across the field to finish a tackle while most of the defense had their hands on their hips watching. Great effort from him.

2:48 p.m. - Smelley getting a lot of snaps at fullback. He's been hammering the point of attack. Not losing many battles up front.

2:45 p.m. - On the first 11-on-11 drill, Upshaw sacks Arizona quarterback Nick Foles. Didn't waste much time there.

2:40 p.m. - William Vlachos just stonewalled former South Carolina defensive lineman Melvin Ingram on a one-on-one drill. Good footwork and balance by Vlachos. Ingram had been very successful this week rushing the passer.

2:36 p.m. - Upshaw just flew by UGA left tackle Cordy Glenn on a one-on-one drill. Showed great burst. The big guys are too slow for his speed rush. And the more athletic tight ends can't handle his bull rush.

2:33 p.m. - DeQuan Menzie looking good at CB and safety. He's adjusted well to the off coverage you have to play in the Senior Bowl. Coaches have praised his footwork and aggressiveness.

2:29 p.m. - It appears Marquis Maze is not at today's practice. He's been at all the practices prior to today, despite a hamstring injury. Trying to confirm if he's still in Mobile.

2:26 p.m. - Courtney Upshaw is the star of the Senior Bowl. He is drawing tons of attention. He's taking a lot of reps and showing great versatility rushing the passer. I'd venture to say he's been the most impressive athlete here on the defensive side of the ball.

2:22 p.m. - Brad Smelley continues to do good work at tight end. I haven't seen him drop a pass all week. Showing good hands and putting in good effort blocking. Could get interest from teams looking for an H-back.
