The offensive line will be a spot where Louisville football coach Bobby Petrino and his staff will focus on in the Class of 2015.
The Cardinals are looking at a bunch of prospects in the '15 class on the line and three of those guys were at practice on Tuesday.
The 6-foot-5, 290-pound Sharp is ranked as the No. 25 offensive tackle in the '15 class nationally and is a four-star prospect. Sharp is a member of the Scout300 and recently went over the 20 scholarship offer mark.
Sharp also has offers from Georgia, Clemson, Auburn, Florida, Georgia Tech, South Carolina, Virginia, Ole Miss and others.
The 6-2,285-pound Jackson is listed as a center and was recently bumped up to a 4-star status by Scout.com.
Jackson has offers from Kentucky and Vanderbilt already.
Lawrence is a 6-6, 285-pound tackle from Trigg County, which is in Western Kentucky.
Cardinal Authority will keep you posted in the recruitment of all three players.
