It doesn't appear that 4* DT Kendrick Norton is going to make it in town this weekend, so that's one less big name on the board. However, he will still probably make it to Auburn before the recruiting cycle is over with.
3* CB, and Louisville commit, Sheldrick Redwine tweeted that he was on the way to Auburn. Auburn offered him in early January, and it looks like he's coming in to town to visit. Don't get hung up on the stars, if the staff likes him, there's probably a very good reason for that. He also has an offer from Charlie Strong at Texas. I'm sure Strong was looking at Redwine from his Louisville days and thinks he'd be a good get at Texas, as well.
4* Auburn ATH commit D'anfernee Mcgriff tweeted to Auburn 4* DB commit Jordan Colbert about the weekend. Mcgriff will be on his official visit according to his Twitter account. I'm fairly certain Colbert has already taken his official visit, but could be mistaken.
4* Auburn OL commit Marquel Harrell will be in town for the weekend. Harrell is from Fairburn, GA, and was recently offered by the Bulldogs, but he doesn't appear to have any interest in leaving the Tigers' fold.
Finally, 2016 lineman Quinnen Williams tweeted that he has committed to Auburn:
<blockquote class="twitter-tweet" lang="en"><p>i just committed to Auburn this morning <a href="https://twitter.com/hashtag/WarEagle?src=hash">#WarEagle</a></p>— Quinnen Williams (@QuinnenD1) <a href="https://twitter.com/QuinnenD1/status/556148355085385730">January 16, 2015</a></blockquote>

There is no official word on that, yet. Williams is an unrated defensive tackle, right now. He's 6'4", 265 lbs. Hopefully we'll know more about that situation before long.
