FRISCO -- Dez Bryant's injury was not diagnosed sooner because the Pro Bowl receiver missed team meetings and a scheduled MRI on Tuesday, multiple sources said.

Bryant underwent an MRI on Wednesday that revealed he suffered a lateral hairline fracture of the tibial plateau of his right knee, sources said. This is where the tibia connects to the knee.

It never made sense why the Cowboys would wait three days after the injury to perform the MRI. It does now.

The players were off Monday, even though injured players are required to report for treatment. When the players reported to meetings at The Star on Tuesday morning, sources said Bryant wasn't among them. Bryant eventually showed up at the facility late in the day, sources said, but too late for a scheduled MRI.

The Cowboys don't have an MRI at their new facility. Once Baylor Scott and White's facility is completed in the same complex, players will simply walk or be shuttled across the parking lot to have an MRI. Until then, they must be scheduled off site.

Club sources said that Bryant has been fined and both sides have moved on. The amount is undisclosed.

Head coach Jason Garrett sidestepped repeated questions over the last two days, refusing to acknowledge whether or not Bryant had an MRI, saying the club was still evaluating the injury.

Garrett said Wednesday afternoon, after dropping in on a conference call to reporters who cover the San Francisco 49ers that Bryant had a hairline fracture, that the receiver is considered day-to- day or week-to-week.

Week-to-week is the more plausible scenario. It's highly unlikely that Bryant will be able to play in Sunday's game against San Francisco. There's a chance he could miss up to three games.

Under that scenario, he would return after the team's bye week when it faces Philadelphia on Oct.30.
