Stanford?defensive lineman Harrison Phillips has been fully cleared to play and is expected to start Saturday at UCLA.?Hes good to go, Cardinal coach David Shaw said Thursday. There are no limitations on him.?Phillips, a junior nose tackle, injured his knee in Stanfords season-opening 26-13 win over Kansas State. The Cardinal initially feared the injury was more serious, so he only missed last weeks 27-10 victory over USC. There even seemed to be a chance Phillips would play against the Trojans late in the week, but Shaw ruled him out Friday.Now, after a productive week of practice, Phillips will be back full-go to anchor No. 7 Stanfords defensive line.He hasnt been gone long enough to get out of shape, and hes been doing great work with the training staff, Shaw said. Im excited about where hes at.The Cardinal are healthy at all other positions entering Saturday.

Spieth and Day were paired together for the opening round McIlroy had made a strong start to the week but faltered over the weekend to finish 10 shots off the pace, while a final-round 68 from Day saw the Australian claim a ninth consecutive top-12 finish.But Spieth once again stole the show and claimed the £7.5million jackpot with a fifth win of the year, seeing him return back to world No 1.September 2015 - BMW ChampionshipDay threatened to post a magical 59 in Chicago on his way to a wire-to-wire victory and his fourth win in six starts, lifting the Australian above McIlroy to top of the world rankings for the first time.A par at the last saw Day open with a 10-under 61 and open a four-stroke advantage over playing partner Spieth, before he extended his lead to five with another birdie-filled 63. Day and Spieth went head-to-head at the BMW Championship Spieth, who had posted an opening-round ace, stuttered over the final rounds to end in 13th spot, as successive 69s from Day saw him cruise home with a six-shot win ahead of Daniel Berger.September 2015 - Deutsche Bank Championship A strong end to the week secured McIlroys return to world No 1, despite needing a final-hole birdie just to avoid missing the cut.Four dropped shots in a five-hole stretch during his second round saw McIlroy scrape through to the weekend, where a closing 66 parachuted him in to a tie for 29th.A first over par round in 22 for Day on Saturday ended his hopes as Rickie Fowler took the title, while Spieths dip in form continue as the two-time major champion suffered a second missed cut in as many weeks.

Spieth became the first back-to-back major winner since McIlroy the previous year After playing alongside Spieth for the first two rounds, Day recovered from collapsing through vertigo late on Friday to shoot 68 the following day and stay in contention.Day would finish the week inside the top-10 despite closing his week with a 74 as McIlroy, who struggled with his putting through the opening three rounds, joined him in a tie for ninth. May 2015 - Players ChampionshipComparisons to McIlroy were short-lived when Spieth missed the cut at TPC Sawgrass, with the American suggesting there was a long way to go before he could be talked about alongside the world No 1. The trio made up the featured group for the opening round of the Players Championship The pair had been joined by Day for the opening two rounds, with the Australian also crashing out early following a second-round 81.McIlroy couldnt find form on the greens throughout the week, eventually closing in a tie for eighth and four strokes adrift of champion Rickie Fowler.
