The San Francisco 49ers got creative in managing some tough cuts Sunday afternoon to get down to a 53-man roster, letting go of their punter and long snapper.But don’t worry, Corliss Waitman and Jon Weeks, neither of whom is subject to waivers, will sign back on Monday as the team continues to tinker with the initial roster.The 49ers could put only two players — receiver Christian Kirk and offensive lineman Austen Pleasants — on injured reserve with a designation to return before Sunday’s 3 p.m. PT cutdown deadline, as part of their effort to reduce the roster from 90 players to 53. They can make more of those moves starting Monday, with linebacker Nick Martin (hamstring), cornerback Nate Hobbs (groin) and cornerback Ephesians Prysock (shoulder) among the candidates.Here are our thoughts on the initial 53-man roster, with plenty of transactions still to come.Rookies in italicsTop Plays from Titans @ 49ersOffense (26)Quarterback (3): Brock Purdy, Mac Jones, Kurtis RourkeCut: Adrian MartinezThe 49ers kept Rourke — despite his three broken ribs — and cut Martinez. That suggests Rourke has recovered enough to serve as the emergency No. 3 quarterback early in the season. Rourke, in fact, could resume practicing this week, coach Kyle Shanahan said. It also signals that the plan to have Rourke at least compete for the No. 2 role next year, with Jones likely to leave as a free agent, remains intact.Running back (4): Christian McCaffrey, Kaelon Black, Jordan James, Kyle Juszczyk (fullback)PUP: Isaac GuerendoCut: Sincere McCormick, Khalil HerbertPutting Guerendo on the reserve/PUP list for the pectoral tear he suffered in the spring means he must miss at least the first four games of the season, though he can resume practicing after Week 2. The 49ers seem as well-stocked at running back as they’ve been in a while. Add Deebo Samuel to the mix, and it ought to reduce McCaffrey’s workload this season.Wide receiver (6): Mike Evans, Deebo Samuel, De’Zhaun Stribling, Demarcus Robinson, Jordan Watkins, Jacob CowingInjured reserve (return designation): Christian KirkCut: KhaDarel Hodge, Will Pauling, Wesley Grimes, Malik Turner, Trenton IrwinThe roles seem largely clear-cut: Evans, Samuel and Stribling will be the top three receivers, while Cowing will serve as the punt returner. The only remaining question is: If the 49ers suit up only five receivers in Week 1, like they normally do, who is the odd man out, Watkins or Robinson?
