The prospect of two of Kentucky’s most important leaders, Derrick Locke and DeQuin Evans, of playing against South Carolina does not look good heading into Saturday.Head coach Joker Phillips listed Locke, UK’s leading rusher, and Evans, one of UK’s defensive captains, as doubtful for the game.  Locke is battling a shoulder stinger he suffered in the third quarter against Auburn, and Evans aggravated a ligament in his ankle.Both would be huge losses as Kentucky prepares to play No. 10 South Carolina, which upset top-ranked Alabama over the weekend.Without Locke, Phillips said they could look to the “Wildcat” formation more this week to keep the running game going. UK used Randall Cobb in the package this week more than it has at any other time this year.”We’ll have to continue doing the things that we’re doing because that’s what we know,” Phillips said. “We also have to use more of the Wildcat, possibly.”Phillips said they used the Wildcat last week with the intention of opening up the passing game. But when Locke went down in the third quarter and the running game continued to open up, Phillips stayed with the package.”The Wildcat package is funny,” Phillips said. “We got in the Wildcat package to throw the football this week. You line up in the Wildcat package and lo and behold, there is the run because we hadn’t been getting it.”Bottom line, Phillips said, is Cobb has to be involved like he was Saturday for UK to break its current skid. Cobb became the first player since Shane Boyd in 2003 to throw, catch and rush for a touchdown against Auburn.”We’ve got to get the ball in his hands,” Phillips said. “Obviously, he is a guy that makes not only plays but huge plays for us regardless if you are dropping back and throwing it, which he did last week by scrambling around and making a play or if you are running it.”Backup tailbacks Donald Russell and Raymond Sanders will also be instrumental in the run game should Locke not play. Russell, a sophomore, has run the ball 27 times for 124 yards this season, and Sanders, a freshman, has 96 yards and three touchdowns on 18 carries. Although Russell was technically demoted on the depth chart before the Auburn game – Phillips said he was “bracketed” with Sanders but was listed third behind Sanders – Russell got nine carries for 32 yards. “I’m proud of Donald, how he handled things,” Phillips said. “We put Sanders in first Saturday night and he missed a few runs, so we wanted to go with Donald. Donald went in there and was seeing well, made some people miss in the secondary (and) did some good things in picking up the blitzes.”
