The AFC Telford United goalkeeper was taken off in the first half of Saturday’s 2-2 draw at Boston United following a collision with Jonathan Wafula.
After being seen by an eye specialist at a hospital in Lincoln, Wycherley was discharged and will now have his progress monitored back at home.
Boss Gavin Cowan said: “We would like to thank everyone for their messages of concern and we will keep you updated over the next few days.”
Joe Bursik came off the bench to replace the 20-year-old – who has been told by doctors to be ‘extremely cautious’ – but the Stoke loanee cannot play in this month’s two-legged FA Trophy semi-final against Leyton Orient because he is cup-tied.
The Bucks led Saturday’s National North fixture through an early Daniel Udoh goal, the striker’s 23rd of the season, but then spurned opportunities to take charge of the game.
Asked whether he regarded it as a point gained or two dropped, Cowan said: “I think the next week or so will tell. We’ve got two home games now (against Darlington and FC United), so I think the result will be defined by those.
"I’ve very mixed feelings; I thought we were very much in control in the first half, but we need to be more ruthless and clinical, which is something I’ve said before and something we’ve got to address.”
There was also another surprise before the game, with Adam Dawson, who left the club for Chester amid some rancour in November, returning on loan from Macclesfield Town for the rest of the season.
