( CNN ) -- This was not in the script . In a season where Real Madrid has appeared irrepressible at times , a 1-1 draw against relegation-threatened Valladolid was not what manager Carol Ancelotti might have anticipated . A ninth minute injury to Cristiano Ronaldo , making him doubtful for this weekend 's game against Celta Vigo and perhaps even the Champions League final , merely rubbed salt into the wounds . Ronaldo appeared to leave the field as a precautionary measure with a hamstring strain before his teammates were forced to settle for a frustrating point against a resilient Valladolid . The result leaves Real four points adrift of leader Atletico , who face Malaga on Sunday before a final day showdown with Barcelona . `` It is practically gone now but while there is a mathematical chance then Madrid are obliged to keep going , '' goalscorer Sergio Ramos told reporters . `` It has been a long season and it takes its toll on the body . `` We wasted a unique opportunity and we will now have to examine it calmly . With 10 minutes to go we relaxed , and against a side battling for survival , they are always going to make it difficult for you , '' The title is now surely between leader Atletico Madrid and second place Barcelona . Should Barcelona defeat Elche , it will need to see off Atletico at Camp Nou to claim the title . Real , which began the contest without the injured Gareth Bale , adjusted to the loss of Ronaldo and moved ahead 10 minutes before the break . Ramos , who has scored five goals in his past four games , unleashed a fine free-kick from 25-yards which flew into the net . The home side , which has struggled throughout the season for goals , improved after the interval and slowly took the initiative . And it came as little surprise when Humberto Osorio headed home Marc Valiente 's corner with five minutes of normal time remaining . The loss of Ronaldo , who has scored 31 league goals this season and 50 in all competitions , will be of greatest concern to Ancelotti . Real faces Atletico in the Champions League final on May 24 in Lisbon and will be keeping a close eye on the Portugal midfielder over the next week . Anceloitti 's side , which takes on Celta Vigo in its next match , finishes the campaign at home to Espanyol on May 18 .
