Haaland came off in the 67th minute of Norway's 2-1 loss to Portugal. Solbakken said it was down to fatigue and workload, not a confirmed injury.
Haaland appeared to be limping before Jørgen Strand Larsen replaced him in Porto, prompting concern ahead of Manchester City's next Premier League match at Liverpool. Solbakken said he and Haaland had discussed possible minute-management scenarios after the forward had played heavily for both club and country.
The Norway coach said Haaland had been tired in the previous match against Wales and was only expected to manage roughly 45 to 60 minutes against Portugal. Haaland did not score against Portugal or Wales, but he had scored in Norway's first two matches of the international window and remains the country's record scorer with 65 goals in 59 appearances.
