Trace McSorley: Joins Steelers' practice squad

Pittsburgh signed McSorley to its practice squad Monday, Adam Schefter of ESPN reports.

The move comes in the wake of reports Kenny Pickett underwent surgery to address his high ankle sprain Monday. Mitch Trubisky projects to start Thursday versus the Patriots, and Mason Rudolph is also on standby, but McSorley could suit up as an emergency option as soon as this week.
