Kansas City Chiefs receiver Tyreek Hill injured his collarbone in the first quarter of the team's season opener against the Jacksonville Jaguars, a source told ProFootballTalk's Mike Florio.
Hill will not require surgery but will miss "a few weeks," a source told ESPN's Adam Schefter.
The 25-year-old appeared to suffer the injury when he was tackled in the first quarter.
He exited after catching two passes for 16 yards.
Hill inked a three-year, $54-million extension with Kansas City days before the season opener. The wideout ranked fourth in the NFL in receiving yards last season, finishing with 1,479 yards and 12 touchdowns.
