Denver Broncos receiver Wes Welker’s fondness for his alma mater, Texas Tech, stretches far and wide. Perhaps a bit too far.Texas Tech is investigating a possible NCAA recruiting violating that involved Welker tweeting a potential recruit who was visiting BYU earlier this month, according to the Lubbock Avalanche-Journal.Receiver Nick Kurtz of Grossmont College in El Cajon, Calif., tweeted “Time of my life right now. Everything I expected and more,” while on an official visit to BYU.Welker replied, “You are visiting Lubbock already?”“At BYU Wes! Hahah,” Kurtz wrote.The possible violation occurred when Welker continued: “Name me the last WR in the league from BYU? Think big picture. I will give you 50 more reasons why [BYU] would be a bad move.”By NCAA rules, Welker qualifies as a booster and “may not encourage a prospect’s participation in university athletics.”Welker’s exchange would likely constitute a secondary violation of NCAA rules which would “provide only a minimal recruiting, competitive or other advantage.”Kurtz, who is 6-foot-6 and 205 pounds, has been offered scholarships at several schools, including BYU, Texas Tech, Cal, Kansas, Illinois and Kentucky.NFL sets bag limitThe NFL is limiting the size and kind of bags fans bring into stadiums, beginning with preseason games. The restrictions are designed to enhance security and speed stadium entry.With the exception of necessary medical items, only clear plastic, vinyl or thick plastic handbags no larger than 12 inches by 6 inches by 12 inches will be allowed.One-gallon clear plastic freezer bags also will be OK, as will small bags about the size of someone’s hand, with or without a handle or strap, that are in a clear plastic bag.Banned items will include purses larger than a clutch bag, coolers, briefcases, backpacks, fanny packs, cinch bags, seat cushions, luggage, computer bags and camera bags.Briefly • Rams: Receiver Tavon Austin, a rookie from West Virginia and the eighth overall draft pick, signed a four-year, $12.75 million contract that includes a $7.6 million signing bonus. • Broncos: Nine-year veteran running back Willis McGahee, who led Denver with 731 yards rushing last season, was released. Rookie running back Montee Ball, a second-round pick from Wisconsin, signed a four-year contract. • Eagles: Rookie QB Matt Barkely, a fourth-round pick from USC, signed a four-year contract. • Steelers: Former Oklahoma QB Landry Jones signed a four-year deal. Jones was drafted in the fourth round and was the last of nine Steelers picks to sign. • Redskins: Defensive end Adam Carriker, who ruptured his right quadriceps in Week 2 last season, told a Washington radio station that he expects to begin the 2013 season on the physically unable to perform (PUP) list as he continues rehabilitation. Carriker, 29, had a second surgery in the winter and his status for the upcoming season is in doubt.
