Former New Zealand international Dan Carter opened up about the injury that forced him off just before half-time of Racing 92's 21-9 loss to Saracens in the European Champions Cup final.
Carter looked to have won a race against the clock to prove his fitness to be involved in Racing's first European final but was forced off after 42 minutes with the same calf injury on Sunday.
In his absence, Racing lost out to Saracens as Owen Farrell kicked the English outfit to victory at Grand Stade de Lyon.
Clearly hampered by his injury, Carter was limping from the start, struggled with his kicking and dropped a high ball under pressure from Farrell.
Carter - who retired from international rugby following the All Blacks' successful Rugby World Cup campaign last year - admitted he had not been doing a lot of training in the weeks leading up to the final.
"I was able to run freely in the warm-up," the 34-year-old said. "It was just before half-time that it really started to tighten up.
"I made the sensible option I was of no help to the team at that stage, hence I decided to come off.
"We left it until the last minute, just do the warm-up and then see how it went, it wasn't getting any worse during the warm-up and that gave me confidence to get out there and throughout the first 30 minutes it wasn't getting any worse.
"I don't think it's anything serious, a couple of weeks. I'll sit down on Monday with the medical team and make a plan, and do the appropriate tests to see what it is.
"It was a big game and you want to give yourself every opportunity to play… to play in a final means a lot, for myself and this team.
"I was confident I could play and that's why I started but it unfortunately didn't last as long as I would have liked."
