After overcoming an injury-riddled 2012 season, the Calgary Stampeders quarterback is dealing with another injury — a strained forearm muscle in his throwing arm this time.
Tate was on the field for Monday's practice at McMahon Stadium. He worked on his footwork, but did not throw the football.
Head coach and general manager John Hufnagel said Tate's status was day-to-day. The coach wasn't sure Tate would be able to play Friday in Montreal against the Alouettes.
"We have to let it settle down," Hufnagel said. "We'll see how long it will take to get him back on the field throwing.
Calgary and Montreal both started the season 1-1.
Tate did not finish Friday night's 36-21 loss to the Saskatchewan Roughriders, leaving with about five minutes remaining.
Veteran backup Kevin Glenn cleaned up in Regina, while Tate stood on the sidelines with an ice pack on his arm.
"There's a little pain there, but we'll see tomorrow, see how it feels," Tate said following Monday's practice.
"Am I confident I will be able to play in Montreal? I'm confident if I am called upon to play, I will play very confidently. If they tell me to go in there, I'm going to fire that ball."
Tate's first full season as Calgary's No. 1 pivot in 2012 was interrupted by injuries, starting with a separated shoulder in Week 2.
Subsequent surgery and rehabilitation sidelined him for all but the final two games of the regular season.
He then fractured a bone near the wrist of his throwing arm in the West Division semifinal win over Saskatchewan.
Glenn was Calgary's starter in the division final victory over the B.C. Lions and in the Grey Cup loss to the host Toronto Argonauts.
Tate said he began feeling pain in his arm a month ago, but completed 19 of 27 pass attempts and threw three touchdowns in a 44-32 season-opening win over the Lions on June 28.
The 27-year-old played an excellent first half in Regina. A pair of touchdown throws and 222 passing yards paced the visitors to a 21-14 lead at halftime. But Tate struggled in the second half and Stampeder penalties also aided a Saskatchewan comeback.
"He was so focused and doing a great job," Stampeder offensive co-ordinator Dave Dickenson said of Tate.
"When he was getting pain in his elbow, it took away from his mental side of the game. He'd be the first to admit it. We lost our flow and it really hurt us."
Tate has become accustomed to questions about his health.
"This is how it is, right? Starting quarterback goes out, everybody has to ask the questions and put it in ink," he said.
Glenn compiled 4,220 yards in passing for 25 touchdowns and a completion rate of 66.7 per cent during Tate's absences last year. The 34-year-old was 4-for-7 for 41 yards in relief of Tate in Regina.
"If was the number one, two or three guy, I'm always going to prepare as if I'm going to play," Glenn said. "I'll just wait to see what happens. I'm ready to go if the situation arises."
