Johnson, 32, arrived in Colorado this week to begin training with the MLS club, having recently been recommended to the coaching staff by ex-Wolves teammate Kevin Doyle, who himself made the move across the Atlantic from Molineux earlier this summer.
The Rapids are in more desperate need of attacking help than centre-back depth at this point of the season – conceding just 22 goals in their 21 games but scoring a league-low 19 – but Bravo admits that that the Englishman’s experience would be a welcome addition to the squad.
“More than anything else, he’s a guy that wanted to come over,” said Bravo. “Obviously, with our backline, I wouldn’t categorize it as a trial. It’s more of seeing what Roger is about.
“If there are any opportunities to strengthen the squad in a position that is strong already, then we’ll look to do it.
“You don’t get [Premier League experience] too often, especially in players that just want to train and get a feeling for what our league is about,” Bravo added. “He’s a vocal guy so he brings a bit of leadership as well. Any opportunity for a player like that to train with our club, see our club and take that message back is important for us.”
Johnson spent the last three months of the 2014-15 campaign at Charlton Athletic, having terminated his contract at Championship rivals Wolves following a torrid four-season spell in the West Midlands.
The ex-Cardiff City man joined the then-Premier League outfit from Birmingham City in the summer of 2011 for around £4 million following the Blues relegation to the second tier, but he would go on to suffer two more relegations in successive seasons as the club dropped down to League One.
Playing his last game for Wolves in May 2013, he had loan spells at Sheffield Wednesday and West Ham United over the following campaign after being transfer listed, and was then forced to train on his own during his final six months at Molineux.
It remains to be seen whether he could offer much to the struggling Rapids, who are sitting bottom of the Western Conference on just 24 points, but at least another relegation would be impossible.
