UNDATED (AP) — Antonio Gates has re-signed with the Los Angeles Chargers for his 16th season. The Chargers today announced a one-year deal with the 38-year-old tight end, the leading receiver in franchise history. In April the Chargers announced they wouldn't be bringing Gates back, but their plans changed when starting tight end Hunter Henry tore a knee ligament during offseason workouts. Gates' 30 receptions last season were his fewest since his rookie year in 2003. He still set the NFL career record with his 112th touchdown reception as a tight end.

UNDATED (AP) — Vegas Golden Knights defenseman Nate Schmidt has been suspended for 20 games for violating the NHL's performance-enhancing substances policy. The penalty was announced by the league today. Schmidt says he did not intentionally take a banned substance and "will not accept being labeled a cheater." The Golden Knights say they disagree with the suspension, and that they believe the presence of a trace of a banned substance was accidental.
