It could be a tough road ahead for veteran forward Scottie Upshall, as the 34-year-old failed his training camp physical with the Edmonton Oilers on Thursday, according to Sportsnet's Mark Spector.

Upshall is attending Oilers camp on a professional tryout offer. While the failed physical doesn't automatically end the tryout, it did reveal a knee injury that will prevent Upshall from participating in the coming weeks.

The Oilers are slated for eight preseason games, beginning Monday against the Calgary Flames, and will open the regular season Oct. 6 versus the New Jersey Devils.

In 63 appearances with the St. Louis Blues last season, Upshall tallied seven goals and 12 assists.
