Callaway (knee) was designated to return from injured reserve Tuesday, Nick Underhill of NewOrleans.Football reports.
Callaway will return to practice this week, opening a 21-day evaluation window for his activation from IR. The undrafted rookie out of Tennessee is eligible to play in Friday's game against the Vikings. With Michael Thomas (ankle) out for the rest of the regular season, Callaway could secure a starting job, especially with Tre'Quan Smith (ankle) not 100 percent.
